Definitions

  • the present invention relates to a process of removing coloured stains from plastics materials by treating with a formulation comprising a salt of sulphophenyl alkyl carbonate.
  • stains especially coloured stains
  • a composition comprising one or more of the following components; bleach, solvent and detergent.
  • peroxide bleaches are often used to remove stains.
  • the bleaches act upon the stained materials, oxidising the stain causing compounds.
  • the oxidation reaction acts in a two-fold mechanism aiding the removal of colour from the stain (by destructive oxidation thereof) and the removal of the stain causing compounds from the substrate.
  • peroxide-containing bleaching agents Due to their utility peroxide-containing bleaching agents have been used in washing and cleaning processes for some time. Such agents are particularly useful in dishwasher applications to aid the removal of foodstuff residues and stains produced on crockery and other kitchenware in cooking processes. Their action is particularly important on coloured stains such as those produced by tomato based foodstuffs and tea.
  • peroxide-containing bleaching agents have been found to perform well at a wash liquor temperature of 90°C and above, their performance noticeably decreases with lower temperatures. Thus when items are washed at lower temperatures, there can be a problem of incomplete stain removal. This is unpleasant from an aesthetic point of view and also can present detrimental hygiene issues.
  • bleach activators catalyse the decomposition of H 2 O 2 .
  • H 2 O 2 or of precursors that release H 2 O 2 , or of other peroxo compounds, the bleaching action of which is unsatisfactory at lower temperatures.
  • acceptable bleaching activity can be obtained at lower temperatures and shorter wash times.
  • Example of a bleach activator include carbonate esters.
  • the carbonate esters react with hydrogen peroxide and peroxide sources to increase bleaching activity.
  • the use of carbonate esters in this way in laundry and textile detergent formulations has been described in, for example US-A-5,043,089 (Akzo NV) and US-A-4,681,592 (Procter & Gamble).
  • a process of removing colour stains from a plastics material characterised in that the stained plastics material is treated in a dishwashing machine with a formulation comprising a salt of sulphophenyl alkyl carbonate.
  • the salt is an alkali metal salt, particularly sodium
  • the sulpho- moiety is disposed at the para position of the phenyl ring.
  • the alkyl moiety comprises an octyl (C 8 ) moiety.
  • the salt of sulphophenyl alkyl carbonate is sodium p-sulphophenyl octyl carbonate.
  • aryl alkyl carbonates are able to react with hydrogen peroxide and also hydrogen peroxide generators and other peroxy compounds to yield a peracid.
  • the reaction pathway for this interaction is shown below (using sodium p-sulphophenyl octyl carbonate for illustration purposes). when exposed to a peroxide source/generator reacts to yield the peracid below
  • hydrophobic component of the sodium p-sulphophenyl octyl carbonate namely the octyl chain
  • the hydrophobic component of the sodium p-sulphophenyl octyl carbonate is able to interact with the hydrophobic plastic surface and the typically hydrophobic staining molecule, this easing its removal and/or bleaching as outlined above.
  • the plastics material is selected from those plastics used in kitchenware items and in the construction of automatic dishwashers.
  • coloured stains especially those stains caused by tomatoes and tomato based products, may be removed from plastic kitchenware and the plastic components of a dishwasher.
  • the formulation is aqueous. Namely the formulation may be dissolved, suspended or emulsified in an aqueous solution.
  • the salt of sulphophenyl alkyl carbonate is sodium p-sulphophenyl octyl carbonate.
  • a concentration in the dishwasher washing or rinsing liquor between 0.01 g and 0.6g/litre, more preferably between 0.01g and 0.4g/litre and most preferably between 0.02g and 0.35g/litre is normally enough to improve the removal of coloured food soils comprising natural dyestuffs from plastic substrates.
  • the degree of improvement is of course influenced by a number of factors like the length and temperature of the washing or rinsing process and/or the composition of the detergent used in conjunction with the component.
  • the amount of peroxide component present in the formulation is most preferably expressed in a molar ration relative to the sodium p-sulphophenyl octyl carbonate.
  • the molar ratio of sodium p-sulphophenyl octyl carbonate to peroxide component is from 1:3 to 1:40, more preferably from 1:3 to 1:20 and most preferably from 1:3 to 1:12.
  • the peroxide component there come into consideration, for example, the organic and inorganic peroxides known in the literature and available commercially that provide a bleach function at conventional dishwashing temperatures, for example at from 10 to 95°C.
  • the formulation contains such a peroxide component.
  • the organic peroxides are, for example, mono- or poly-peroxides, especially organic peracids or salts thereof, such as phthalimidoperoxycaproic acid, peroxybenzoic acid, diperoxydodecanedioic acid, diperoxynonanedioic acid, diperoxydecanedioic acid, diperoxyphthalic acid or salts thereof.
  • organic peracids or salts thereof such as phthalimidoperoxycaproic acid, peroxybenzoic acid, diperoxydodecanedioic acid, diperoxynonanedioic acid, diperoxydecanedioic acid, diperoxyphthalic acid or salts thereof.
  • inorganic peroxides are used, for example persulfates, perborates, percarbonates and/or persilicates.
  • Percarbonate and perborate are particularly preferred.
  • hydrogen peroxide may be incorporated into the formulation.
  • a stabiliser and / or a thickener may be required to provide, for example, adequate stability (i.e. shelf-life) of the hydrogen peroxide.
  • hydrogen peroxide is used, for stability reasons, it may be separated from the rest of the formulation in a separate portion.
  • peroxides may be in a variety of crystalline forms and have different water contents, and they may also be used together with other inorganic or organic compounds in order to improve their storage stability.
  • the formulation will include in addition to the sodium p-sulphophenyl octyl carbonate and peroxide component any other conventional detergent ingredient including but not limited to compounds belonging to the classes of surfactants, builders, bleaches, bleach activators or bleach catalysts, enzymes, solvents, fillers, tarnishing or corrosion controlling ingredients, perfumes and dyes.
